Letters Patent Ng. 81,527, dated August 25,1868.

IMPROVEMENT IN THILL-GOUPLING.

TO ALL WHOM IT MAY GONCERN:l

Be it known that we, ELI M. MORRISON and JAMES K. ROSS, of Noblesville, in the county of Hamilton, and the S'tateofIndiana, have invented certa-in new and useful Iuiprovements in Thill-Coupling; and do hereby. declare that the following is a full, clear, and exact description thereof, reference being had to the accompanyingY drawings, and to the letters of reference marked thereon.

The nature of our invention consists in providing one or both ears of an ordinary carriage-clip withgrooves or key-seats, and the inner side, between said ears, with rubber packing; and also in shaping the end of the thill-iron eccentrically, and providing the same with a similar groove or key-seat, and in securing the thill-iron to the clip by meansv of a pin or bolt, which is provided with one or two keys, `to tit into said grooves or keyseats on` the thill-iron and ears of the clip.

By this arrangement, the thills or shafts can be removed or changed with great facility, simply by raising the shafts till the key or keys on the pin are on a line-'with the grooves or key-seats in the clip, and removing Vthe pin, and, while in use, the pin o'r-bolt cannot by anymeans be misplaced or lost, as there are no screws to wear or nuts towork off, as in those ordinarily used.

In'order to enable others skilled in the art to make and use our invention, we will now proceed to describe its construction and operation, referring to the annexed drawings, which form a part of this specification, and in whicl1- Figure 1 is a sidesectional view,

Figure 2 a plan view, and Figure `3 a side view of the pin or bolt. A represents an ordinary clip for a carriage, so constructed as-to dt the axle on the vehicle, and providedy withtwo ears, B B. i The inner side of the clip, between the ears, is provided with rubber packing C, so that the end ofthe thilliron will fit tight into the clip, and prevent any rattling.

One of,the ears B is provided with a groove orikey-seat, a, on the rear side of the hole through which the bolt paseos.

E is a thill-iron, also provided with a groove or` key-sent, I), on theV upper side of 'the hole through which. the pin or bolt passes. 'lhe end et' this thill-iron is shapedeeeentrieally, so that the rear part thereof, when it is in its proper position, is thicker than the rest, and presses against the rubber packing C, as shown in fig. 1.

The pin or headed bolt D is provided with a. key, e, to I it into the grooves a and 6. I

When uthe thiil-iron E is raised perpendicular-ly, the groove b'wi'll be on a line with the groove a, in the ear of the clip, and thc bolt D can casily'be put in, and when the thill-ron is turned down in a horizontal position, I

the eccentric end thereof will press Aagainstthe rubber packing. y

There may be two keys instead of one on 'the bolt, in which case the groove or key-seat must be cut through both ears of 4the clip, and the second key will come through on the outside of the ear. This .is thought to be necessary, in heavy vehicles, to keep the ears of the clip from spreading apart.

We do not claim the mode of securing the thill-iron E to thevcarriage-elip by means of the bolt D, provided with a key, c, lto iit in grooves on said thill-ron and clip, but the manner in which the end of the thill-iron is shaped, so that, in combination with the rubber packing C, it will press against the bolt, and prevent rattling.

I'Iaving thus fully described our invention, what we claim as new, and desire to secure by Letters Patent, is-

The eccentrically-shaped thill-ii'on E,i'n combination with the carriage-clip A,Arubber packing C, and bolt D, constructed as described, and operating substantially as and for the purposes herein set forth.

In testimony that we claim the foregoing, Wehave hcrcunto'set our hands, this 13th day of May, 1868.
